J7 pro Galaxy Apps issue after Oreo Update

[EZ]

I am facing issue while opening "Galaxy App" to update samsung apps But its saying unable to open/stopped.
I have cleared app data from settings and then the app opens but doesn't sign in. Again exiting the app and reopening shows the same error.

Anybody else facing the same issue? Can you suggest me any resolution for the same.
